We at the Southern Arizona Limb Salvage Alliance (SALSA) have long embraced the benefits of interconnectivity and open source solutions. Surgical planning and collaboration are no exception. The concept of 3D surgical “printing” (templating and simulation) in lower extremity reconstruction is not entirely commonplace. This is likely for a number of reasons. With the continual maturation of free and open source software applications as well as the ever increasing capabilities of “RepRap” technology (see http://reprap.org/wiki/Main_Page ), we can overcome these limitations.
